I have a tv Sony Trinitron XBR. It does not turn on; the LED red light blinks 7 times.

There were times that I was able to turn the tv on after pressing the power button on the remote control many times. When I turned the tv off, and then on in a few minutes, the tv would still turn on. But when I left the tv off for hours, the tv would not turn on again. Usually the red light flashes 7 times, but there was one occasion, it flashed for 6 times repeatedly.

I think I have the solution for you. I have the same tv and it does the
same thing when you turn on the power button on the remote when the tv
turns on you hear a click then the red light flashes about 5 to 6 times
then the tv comes on. on the remote there should be two buttons on top
of the remote one says power and the other one says system hit the
power button to turn on the tv when you hear the click and see the red
light flashing then hit the system button which will turn off the tv
then hit the power button again and it will turn the tv on without the
red light flashing it should work

I
know this isn't what you want to hear, but the problem you've
described can't be fixed with troubleshooting.
Your TV
will have to be repaired. There is a part that has developed a defect
and needs to be replaced. If you're still in warranty, the TV will be
repaired at no charge to you. The warranty would likely be at least
one year from the date of purchase from the manufacturer. If you
purchased an extended service
plan
they will repair the TV at no charge as well.

If the TV is no
longer in warranty, it will likely cost a minimum of $150 parts and
labor. This is assuming that you only need one circuit
board
or small part. If the problem is more than one of the circuit boards,
the price of repair could go much higher.

Unfortunately, what you're describing is a repair
issue. You won't be able to address the problem with troubleshooting.
There is a part inside the TV that needs to be replaced. If you're
under warranty, this will cost you nothing. If you're not under
warranty the cost will likely be a minimum of $200 parts and labor.
However, be warned that the cost could be considerably higher.

Blinking of standby LEDs to Sony TVs are fault indications. Form the number of blinks occur at one time, the repairman can get an idea of the faulty stage inside it. According to you, it blinks 4,6 & 7. Just visit this site, It has details about blinking codes to Sony TVs, both CRT based, Flat panels and Plasmas. I can't provide more advice to you, because the number of blinks are not constant. Check the site, and get it.

COULD YOU PLEASE HELP ME OUT ,I'VE TRIED CUTTING THE TV OFF FOR ABOUT 6 HOURS AND CUTTING IT BACK ON,SAME RESULTS, THANKS

In cannot remember if this model of set uses on the CRT drive board a drive IC for the CRT colour channels, or if it uses descrete transistors. I have had component failure on this board that causes your description. The failure in your case would be with the red channel drive. Most of the time I had the semiconductors fail, and some of the support components.

Most of the time, a failure on this board is caused by some intermittant internal arching inside of the CRT. If this happens, the CRT is starting go defective.

Another cause of this fault is that the CRT is starting to go internaly shorted between the control grid and screen grid. As it heats up, the shorting becomes lower in resistance, and thus causes the pricture to go brighter until the protection turns it off. This would be with the red electron-gun.

With any failure with the CRT, the set is not worth to fix even if you can find a CRT for it.

The 6 or 7 blinks usually indicate a problem in the horizontal circuit. Since the TV recovered once, the problem is most likely to be a bad solder connection in that area. If you can solder, resolder any connections on the board that appear grainy or have rings. That may resolve the problem. If not, update this and we'll look elsewhere for defective parts.
